Abstract

A cast-in-place concrete pipe system comprising at least one outer barrel, at least one inner barrel, at least one reinforcement dowel used to create a reinforcement cage, at least one reinforcement wall separator, at least one coupling ring, at least one fill port, one or more barrel support stands and a concrete mixture that is poured into the fill port to reside in the space between the outer barrel and the inner barrel.
